Problem with OpenGL
Hey, I recently installed Kubuntu on my computer and when I try to open up HL2 EP. 1 I get this error message: "Could not find required OpenGL entry point 'glcolormaskindexedext'! Either your video card is unsupported, or your OpenGL driver needs to be updated." Any suggestions?

Could be lots of things, your card could be old and not have OpenGL 3+, your driver could be not correctly isntalled etc. I had this when I manually installed the video drivers, which by itself a bad mistake.
Since you didn't post your hardware specs I'll point to some threads that MIGHT help.

This problem is very old, I found thread that might help.

Just read it backwards.


- Any suggestions?

Wow, that's some pretty old hardware, I'm not sure if I know a distro that has good drivers for that card.

OpenGL 2.0 = No Steam On Linux for you.

Yes you need to have at least OpenGL 3.0 capable hardware.

I think you need OpenGL 2.1

You could try the workaround posted above but from what I remember it was only ever tested on Nvidia hardware.

To be honest though the Radeon Xpress 1150 probably can't run HL2 EP1 on Windows at a playable frame-rate even if you used the lowest settings at 640*480. Using a hacky workaround to get the game to run on Linux isn't going to improve the performance any.

Nope OpenGL 3.0. If you only needed 2.1 I could play games on my 7 years old laptop.

It can be confusing. The lowest series of Geforce cards that Source games support is the 8*** series. Nvidia's website still lists those cards as only having OpenGL 2.1 support. However that's simply because that was all that was available when the cards were first released (OpenGL 3.0 coming a few months later). It turns out however that the 8*** series cards actually support OpenGL 3.3.

Nvidia really need to update their website...

When I had windows on my computer I could run it at almost full settings lol

I think it's something to do with their wrapper. While the game can run in Windows on older hardware using DirectX 9, the wrapper they use to 'port' it is OpenGL 3.0+.
Which makes sense from an OpenGL development perspective as the changed a lot of things in 3.0 and depreciated the older API stuff that was removed around around 3.2 or so - there's little point in supporting pre-3.0 hardware that is now obsolete.

That's because you can still install the drivers on Windows, on Linux it's not possible to install AMD drivers which are that old unless you run an os that is not supported anymore.

You have 3 choices:

1. Not playing at all. (Well, you can still play GoldSrc games and some indies. At least my DX8 capable Ti4200 can run them under linux.)
2. Playing using windows.
3. Buying a (maybe second-hand) PCIe card that has the required features.

you can use Wine to run most older games running on Old hardware
